A ball is thrown upward from the ground with an initial speed of vi = 5 m/s. Ignore air resistance.  Calculate the ball’s total time of flight, in seconds, from its launch to its return to the ground.

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 5.89 m/s. The stone subsequently falls to the ground, which is 13.1 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s2 for the acceleration due to gravity. impact speed: How much time is the stone in the air? elapsed time: m/s

3. In Physics, the height of a free-falling object at a given time t is given by h = –16t² + v,t + h., where v, is the initial velocity, and h, is the initial height. A student throws a ball upward from a height of 48ft, initially at 32 ft/s. What is the maximum height of the ball?

The ball falls a vertical distance of 11.6 m into a lake below. (a) How much time does the ball spend in the air? (b) What is the speed v of the ball just before it strikes the water? Ans: 1.54 s; 18.36 m/s

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.71 m/s. The stone subsequently falls to the ground, which is 16.7 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s² for the acceleration due to gravity. impact speed: m/s How much time is the stone in the air? elapsed time: S

rocket, on an unknown planet, launches straight upward. Starting from rest, the rocket accelerates until it reaches 25 m/s then maintains that velocity until its boosters shut off. It eventually falls back to the planet. ASSUME: Starting at t = 0, the rocket accelerates upwards a total distance of 10 m, where it reaches an instantaneous velocity of 25 m/s The moment it reaches an instantaneous velocity of 25 m/s, it travels 30 m upward at a constant speed, then the engines cut off. The moment the engines cut off: the rocket is in free fall From the time it initially launches (t = 0) to the time it lands back on the planet is 7 s The acceleration due to gravity is constant on this planet. HOWEVER you may not assume g = 10 m/s2 Air resistance is negligible DETERMINE: The acceleration due to gravity on this planet

10:   A bullet is shot straight up into the air from ground level. It reaches a maximum height at h = 366 m.    (a)  Calculate the initial speed of the bullet, in m/s.   (b)  Using your previous results, calculate the total flight time, tt in seconds, until the bullet reaches the ground.

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.61 m/s. The stone subsequently falls to the ground, which is 17.3 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. A) Impact speed: _________________________ m/s     B) How much time is the stone in the air? elapsed time: ____________ s

tortoise crawls the entire 1000.0 meters at a speed of 0.20 m/s. The rabbit runs the first 200.0 meters at 2.0 m/s, stops to take a nap for 1.3 hours, and awakens to finish the last 800.0 meters with an average speed of 3.0 m/s. Who wins the race and by how much time? Get to destination at the same time. Rabbit wins by 47 s Tortoise wing by 47 s O rabbit wins by 2.02 hrs Tortoise wins by2.02 hours
